German nukes weren't built in places where we can expect toxins to have been dumped. Look on a map: they were built in rural areas.
Your theory depends on the information from the power stations being correct. The text you put in bold. Implicitly you say that the industry can be trusted to inform us correctly about radiation and radioactive particles being set free. Really, Thomas, isn't that naïve? Melo has already pointed that out.
As to the impact of Chernobyl, I recommend you look at all data about deaths and anomalies of newborn babies of that period, and all over Europe. There are enough data.
As to rural dumping, I live 30 klicks from a major remediation project. - a plantation that was established in 1860 to limit sand dune migration, and used to dump waste from paint production in 1920s. Utterly poisonous to this day, and picked as a dump site because it was not near people, and that was the height of enviormentally responsible thought back then. Germany industrialized earlier, is a world center of chemical industry, and fought two world wars (Which was not good for record keeping! or responsible industry during). The first instinct when you see a spike in cancers anywhere in germany really should not be to blame the nearst reactor. It should be to test the soil and water. There is probably something there, and that means it might well be fixable.
